Beautiful interface, good sounds (could not hear any loop points yet), multiple variants of sounds (e.g. different rain sounds). I couldnt find another app with so many good sounds for free! If this good impression is still the same in a few days, I will go and buy the pro version with even more sounds. However, there are also some problems: - interface is sometimes unresponsive for a few seconds (although sounds are never interrupted) - master volume control is missing to turn all sounds down e.g. when watching eyeTV! - I dont like the "binaural sounds". They dont seem to do anything for me but give me a headache. Luckily you dont have to use them ;). - the alarm does not work when the mac is in sleep mode All in all a great app with some room for improvement.
